305-036-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-036-556-203 is a standard card edge connector designed for dual-edge board applications. It features 36 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator. It supports PCB thicknesses of 1.57mm and operates within a temperature range of -40°C to +105°C. The component is RoHS compliant and classified under MSL Level 1.

Edgeboard Connectors Feature Summary

• Dual-row receptacle configuration for non-specified dual-edge cards
• Gold-plated contact surfaces for reliable signal transmission
• Thermoplastic polyester housing for structural stability
• Vertical panel mount design for secure installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation boards
• Automotive electronic modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to ensure correct termination style and flange options. Confirm that the target PCB thickness aligns with the specified 1.57mm requirement. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure storage conditions respect the moisture sensitivity level to prevent soldering defects during reflow processes.

Edgeboard Connectors Selection Notes

Select this model when a vertical panel-mount solution is required for dual-edge circuit boards. The 0.156-inch pitch accommodates standard high-density layouts. Consider the 5A current rating and 5 GOhms insulation resistance for electrical safety margins. Compare against the 305 series variants for alternative mounting styles or pin counts if the exact specifications do not match the design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and mounting configurations. The 305-036 variant specifically addresses mid-range density requirements. It is distinct from the 387 series which typically features different termination methods. The product line emphasizes durability and consistent performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing mating cards before substitution. Cross-reference with other EDAC series such as 333 or 387 only if mechanical dimensions and electrical ratings are fully compatible.
